Question

我正在尝试使用php 7.0，因为每个人都建议我从这里开始，因为5.6已被删除。但在编写代码后，我无法从数据库中获取值。我在这做什么错。谢谢

//这是我的约会页//

<div class="col-lg-10">
    <?php  include('config.php');
    $query = mysqli_query('select * from about ');
    while($row = mysqli_fetch_array($query)){
    ?>

    <h5>
    <?php echo $row['about_desc'] ;?>
    <br>
    <br>
    <?php echo $row['about_desc1']; ?>
    <br>
    <br>
    <?php echo $row['about_desc2'] ;?>
    <br>
    <br>
    <?php echo $row['about_desc3'] ;?>
    <br>
    <br>
    <?php echo $row['about_desc4']; ?> 

    </h5>
    <hr class="featurrate-divider">
    <?php
    }
    ?>
    </div>
</div>

<div id="tab-1">
    <?php  include('config.php ');
    $query = mysqli_query('select * from news LIMIT 0,2');
    while($row = mysqli_fetch_array($query)){
    ?>
    <div class="news">
        <h4><u><?php echo $row['news_name']; ?></u></h4>
        <h5><font color="black"><?php echo $row['dat']; ?></font></h5>

        <p><?php echo $row['news_desc']; ?></p>
        <a href="index.php?con=8">se mer >></a>
    </div>
    <hr class="featurrate-divider">

    <?php
    }
    ?>
</div>

//这是我的config.php文件//

<?php
$connection = mysqli_connect('localhost','root','','dandelion') or die(mysqli_error($connection));
?>

如果您的数据库连接成功完成，并且获取数据的问题比使用number.it可能对获取数据有用。

circle.setPosition( window.getSize().x / 2 , window.getSize().y / 2 );

<?php echo $row[o]; ?>

而不是

<?php echo $row[1]; ?>

Mysqli查询不提取数据库值
